This is exactly the kind of discussion I was hoping to start. I don’t agree with spending over 400 on a electric Water pump because its not very practical but what I would spend around 250$ for a lsx electric water pump that flowed 40-45 gph and I’m sure I’m not alone in that. I have some ideas on how to accomplish this but I need a old water pump to try it on

But....you aren't the first one to attack the problem. It started with an electric motor driving a belt that spun the stock water pump. Lot's of these were sold by Moroso and were used at the dragstrip on race cars to cool them down in the pits while the engine was shut off. You can still buy them. But the electric motor couldn't spin a stock water pump fast enough to keep up on the street.

Over the years the electric water pump has evolved into what is available today. The stock water pump was replaced by a purpose built pump designed to be driven by a electric motor all in one piece. Yes, they're expensive, but they're light years ahead of the old electric motor driving a belt driving a stock water pump.

I still have a car with a cement truck electric water pump on it (the pump they use to wash the truck down with when they finish pouring cement). It's the same pump they use on house boats to pump water to the kitchen and bathrooms. It works better than the old belt driven electric setup sold by Moroso, but not as good as what you can buy today. The car hasn't been started in years, but if I get interested in it again and the cement truck water pump ever quits or I decide to do some major work on the car, I'll be moving on up to one of the new high dollar pumps.

In the end you get what you pay for. You wanna play you gotta pay.

I took your advice for what you were saying in your first post about those belt driven elt. water pumps were for and did more research and the idea has evolved. I found a good used water pump and will be trying the idea out. if you want to play you have to pay is correct but if you fab something up you’ll be paying less:chevy:

Or you might end up paying more if it doesn't work and you end up with a pile of worthless parts. But sometimes that's what hot rodding is all about. I've tried lots of stuff over the years I wasn't sure about. If you can get something a little off the wall to work it feels good.

If you can get your water pump idea to work well enough to use, more power to you. Good luck.

If your going to even try for some type of electric pump, go out and buy the complete pump from meziere.. They make them for a daily, have a 2000+ hour life exp.. Of course it is going to draw a lil bit more on your electrical system, but nothing that is going to overload it. Like QUICK said, elect fans pull more amps. That pump might draw 5 amps.. Think of the stereo systems we have in out trucks, with the stock Alt?? I wouldn't be scared to do it, if I had 600+ buks that I didn't need.. It is worth it you want every HP you can get.. Its on my list, but not till I get other things taking car of first..
